TOOL FOR REPAIRING STAR'DER MECHANISMS.

throughout the same, The manner of using my tool is as fol- Figure I is a side elevation of my tool as lows the same appears in use upon a Bendix Assuming that it is desired to place a comstarter, pression head such as designated at 23 of Figure II is a front elevation of my tool, Figure IV, upon a Bendix drive, the end of Figure III is a top plan view of Figure II, which is shown at 24, it is first necessary to Figure IV is a fragmentary detail view place the compression member upon the showing a compression sleeve before and Bendix drive, after which the whole device is after crimping.

This Bendix and rotating the same, pressure is brought to 55 drive has a compression head which is robear upon the plug 18 with the result that tatable with respect to the remainder of the the crimping wheel. 19 is forced against the surface of the compression member. By now grasping the handle 12, and rotating the casting 5, it will be evident that the crimping wheel will be caused to rotate around the compression head which is being held against rotation by the rod 9. In this manner it is possible to crimp the compression head at any point desired.

In some Bendix drives, it is necessary to employ a spacer ring 32 (see Figure IV). This ring is employed as indicated in dotted lines in Figure VI with the result that the head as a whole cannot enter the tool asfar as it otherwise would.

When it is desired to remove the nipple 36 from the Bendix, the same is grasped in the jaws of the vise as shown in Figure V after which the tool is employed in a reverse position as shown in this figure. By now inserting the screw 27 so that the same protrudes from the side of the Bendix to form a lug,

' it will be apparent that by rotating the tool counter-balance gear 37 from being the Bendix as a whole will be unscrewed from the nipple 36 thereby preventing the unscrewed from its thread 38.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the shape, size, material and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claim 1. In a tool of the character described, a casting having a pair of axially aligned bores formed therein, a partition separating said bores, a rod carried in said partition and being centrally disposed within one of said bores, a pin positioned within said rod and in close proximity to said partition and a crimping wheel slidably mounted in said casting and adaptedto have a portion of its periphery extending into one of said bores,

2. In a tool of the character described, a casting having a pair of axially aligned bores formed therein, a partition separating said bores, a rod carried in said partition and being centrally disposed within one of said bores, a pin positioned within said rod and in close proximity to said partition, a crimping wheel slidably mounted in said casting and adapted to have a portion of its periphery extending into one of said bores, and means for moving said crimping wheel for the purpose specified.

In testlmony whereof I aflix my signature.
